Sanders Fashion Company enters into a lease arrangement with Highpoint Leasing for 5 years. Sanders agrees to pay 4% of its net sales as a variable lease payment. Sanders does not pay any fixed payments. Sanders is a highly successful company that has achieved over $1,000,000 in net sales over the last 7 years. Both Sanders and Highpoint forecast that net sales will be a much greater amount than $1,000,000 in subsequent years. As a result, it is highly certain that Sanders will make payments of at least $40,000 ($1,000,000 4%) each year. What is the lease payment amount Sanders should use to record its right-of-use asset?
